Summary
This is a multicenter, open-label, controlled, single-blind, randomized study with up to 452 subjects enrolled in up to 50 US and European sites. Subjects who present with anterior ST-elevation myocardial infarction (STEMI) and an occluded proximal or mid left anterior descending (LAD) with TIMI 0/1/2 flow will be eligible for randomization to one of the following arms:
1. Local infusion of abciximab following thrombus aspiration
2. Local infusion of abciximab and no thrombus aspiration
3. No local infusion and thrombus aspiration
4. No local infusion and no thrombus aspiration
In addition, a cardiac magnetic resonance imaging (MRI) sub-study evaluating microvascular obstruction (MVO) will be performed with up to 160 subjects at up to 20 sites.
Eligibility Criteria
Key Inclusion Criteria
- The subject must be >18 years of age;
- Subject is experiencing clinical symptoms consistent with AMI (e.g., chest pain, arm pain, etc.,) >30 minutes duration and unresponsive to nitroglycerin;
- Anterior MI with ECG showing at least 1 mm of ST-segment elevation in 2 or more contiguous leads in V1-V4, or new (or presumably new) left bundle branch block;
- Anticipated symptom onset to balloon or aspiration time of ≤5 hours;
- The subject and his/her physician are willing to comply with specified follow-up evaluations;
- The subject or legally authorized representative has been informed of the nature of the study, agrees to its provisions and has been provided and signed written informed consent, approved by the appropriate Medical Ethics Committee (MEC) or Institutional Review Board (IRB)
- Infarct artery located in the proximal or mid left anterior descending coronary artery, with TIMI 0/1/2 flow at the time of initial diagnostic angiography (prior to wire passage);
- Based on coronary anatomy, PCI is indicated for revascularization;
- Only one epicardial coronary artery will be treated;
- Expected ability to deliver a ClearWay™ RX Infusion Catheter to the infarct lesion (absence of excessive tortuosity, diffuse disease or moderate/heavy calcification).
Key Exclusion Criteria
- Prior myocardial infarction, or known prior systolic dysfunction (known ejection fraction 40% or that will require intervention
